5 Claims.

@illustrated in the accompanying drawings a preferred embodiment of my invention which will now be set forth in detail in the following description and particularly defined in the claims appended thereto.

In said drawingsz- Figure 1 is a top plan view of a platen frame and at platen illustrating the application of my invention,

Figure 2 is a fragmentary view in longitudinal section taken on the line 2-2 of Figure l, and drawn on an enlarged scale,

Figure 3 is a fragmentary view in transverse section taken on the line 3--3 of Figure 1 and drawn on an enlarged scale,

Figure 4 is a perspective view of a guide member formingv a part .if my invention,

Figure 5 is a perspective view of a slide member, another component of the invention, and

'Figure 6 is a detail View in side elevation of a portion of said slide member.

In the drawings, my novel work feeding means has been shown as applied to the at platen of the well known Elliott Fisher machine of commerce. The platen 1 of this type of machine is usually provided with a rubber or other resilient top layer la and is mounted, for vertical movement, by means not shown, toward and from the writing plane, in a platen frame 2 including side and end members 3 and 4, respectively. The

side members 3 provide the usual tracks 5 for the travelling line space frame (not shown) of the Elliott-Fisher machine, and have mounted thereon line space racks 6 to which the line space frame (not shown) is geared, as will be understood.

The element designated '7 is one of the guide rolls with which these machines are equipped for guiding endless forms over the platen, and 8 is a paper table for facilitating removal of forms or work sheets from said fplaten, all of which are well known in the art and need merely be noted in passing. For a detailed disclosure of the platen moving mechanism, line space frame, etc. of the Elliott-Fisher machine, attention is directed to my Patents Nos. 1,207,152 and 1,236,420.

When the platen 1 is elevated in this class of machine, it acts to clamp a work sheet, or sheets, or a form, as the case may be, against clamping bars 9 projecting from the side members 3 and overhanging the side edges of the platen.

According to my invention, a base member 10 in the form of a guide, substantially coextensive in length with the platen, is mounted on the face of the top layer la lengthwise of the platen, which is to say, in the direction of line spacing, and adjacent one marginal side edge thereof. The base member 10 is preferably formed of a strip of suitable metal having its side edges bent over to provide grooves 1l open at their ends.

At suitable points in its length, the base member 10 is apertured as at 12, the metal around the apertures 12 being punched outwardly to provide frusto-conical sockets 13, (Fig. 3) and the platen is provided with correspondingly located threaded bores 15 terminating in frusto-conical seats 16 in which said sockets 13 seat to prevent the base member 10 from creeping. Suitable screws 17 secure the base member 10 to the platen, the heads of the screws seating in the sockets 13.

A sliding work carrier 18 in the form of a flexible tape, or a rigid flat bar, as preferred, is mounted on the base 10, with its side edges travcling in and guided by the grooves 11, said carrier having upstanding studs 19, whereby a work sheet or form 20 having marginal openings may be disposed thereon, as will be understood, to bel moved therewith over the platen. A finger piece 21 is provided on the front end of the carrier 18 for convenient manipulation of said slide and sheet or form to manually feed the latter over the platen.

Preferably, as shown in Figure 3, the clamping bar 9 adjacent the base member 10, is undercut to provide a lip 22, and said base member 10 is located so that said lip 22 overhangs the contiguous marginal edge of the carrier 18, and hence the marginal edge of the work sheet 20, whereby said sheet or form, in the elevated position of the platen, is retained on the studs 19, it being understood that sufficient clearance is provided between said lip 22 and base member 10 to permit the free movement of the sheet or form.

The foregoing is a detailed description of a preferred form of my invention, and it is thought that tuff its operation will be understood therefrom. It is to be understood that right is reserved to such modifications of the structure described as fall fairly within the scope of the protection prayed.

What I claim is:

1. The combination with a platen depressible from the Writing plane, of Work feeding means, including a guide member mounted upon the platen for depression therewith, a work carrier mounted on the guide for sliding movement, and a nger piece for use in moving said carrier.

2. The combination with a at platen depressible from the writing plane, of a Work feeding member incorporated with the platen for sliding movement over the surface thereof and for depression therewith. Y

3. In` combination, a iiat platen depressible from the Writing plane, and Work feeding means,

ing a strip-like rigid member incorporated with the platen and adapted to engage the perforations in the sheet, and a sheet retaining element overhanging said strip and spaced therefrom to provide a clearance for said sheet.
